Suppose you have three events - X, Y, and Z - where X and Y are mutually exclusive, and together X, Y, and Z are collectively exhaustive. Z is not mutually exclusive with respect to either X or Y. Is this possible? If so, draw a Venn Diagram illustrating how it might be possible.
Homework Answers
X and Y are mutually exclusive events that is both cannot occur together means there in nothing common between two of them.
X,Y and Z are collectively exhaustive that is atleast one of the event must occur.
Z is not mutually exclusive with either X or Y that is there is some common part between X,Z and Y,Z .

Suppose three random variables X, Y, Z have a joint distribution PX,Y,Z(x,y,z)=PX(x)PZ∣X(z∣x)PY∣Z(y∣z). Then X and Y are independent given Z? True or False Suppose random variables X and Y are independent given Z , then the joint distribution must be of the form PX,Y,Z(x,y,z)=h(x,z)g(y,z), where h,g are some functions? True or false

Problem 1. Consider the two data collections (x,..-, X) and (y,. ya). The median difference statistic is the median of the (v-x) differences for the mn possible (x, y.) pairings, i= 1, ..., mandj = 1, . . ., n. Construct two specific data collections (x,. Xm) and (y,. .. V) that demonstrate that the median difference statistic is not equal to the difference in the separate medians for the two collections Problem 2. A Venn diagram is a graphical...
